ROLLER-FILLER FOR BEARIN Specification of Letters Patent.

Patented Oct. 4, 1921.

Application filed October 22, 1919, Serial No. 332,556. Renewed January 17, `1921. Serial No. 437,965.

To all whom t may concern:

Be it known that I, LEONARD BARTLETT, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Roller-Filler for Bearings, of which `the following is a specification.

This invention relates to bearings, and especially to so called oilless bearings in which a perforated bearing, or a bearing having a plurality of pockets containing lubricating plugs is used; and the object of the invention is to provide means to mount the lubricating plugs in the bearing in a simple and elicient manner with a minimum of expense.

The invention is illustrated in the accom-` panying drawing in which- Figure l, is a sectional elevation of a roller filler constructed in accordance with my invention;

Fig. 2, is an end view of the ller, with a part of the holding casing removed; and,

Fig. 3, is a sectional view of the bearing.

In the drawing, like numerals of reference refer to the same parts in each of the views.

In the practice of my invention I provide two supports, one for the mandrel and rotating shaft 4, a part of which is shown at 5; and a holder for the rollers 6, indicated at 7, while the filler casing 8 is vslidably mounted on the rollers 6, and carries the hopper 9, in which may be mounted the lubricating material adapted to fill the pockets in the bearing, as hereinafter described.

The casing 8 is movable on the rollers 6 l longitudinally, and is under the control of the operator in connection with the yoke 10 and the rollers 11 adapted to travel in the groove 12 of the casing 8.

The rollers 6 have semi-conical ends 13, on which the casing 8 is mounted; and the rollers have each a conical part 14 on which the other end of the casing 8 is slidably mounted, for purposes hereinafter eX- plained.

The part of the bearing carrying the lubricating plugs are indicated at 15, in Figs. 1 and 3; and the lubricating plugs are indicated at 16 in these figures. It may be explained that the device is adapted to mount lubricating plugs in a bearing of the character described in my application for Letters Patent of the United States tiled Qctober 17, 1919, Serial No. 331,376.

In operation the lubricating powder is placed in the hopper 9; and is fed to the bearing through the perforations 17 above the rollers, while perforations 18 at the bottcm of the casing 8 permits the surplus powder to escape. As the lubricating powder descends through the perforations 17 from. the rhopper it is pressed into the pockets of the bearing to form the plugs 16. It will be understood that in this operation the mandrel 4, on which the bearing part 15 is mounted, is rotatable at the will of the operator by bringing the part 19 of the machine, having the clutch 20, into engagement with the shaft 21 of the mandrel 4; while the operator can slide the casing 8 backward and forward on the rollers 6 with the yoke 10. It will be understood, too, that as the casing 8 has fixed end walls slidably mounted on the rollers 6, sliding the casing one way will drive the rollers inward on account of the conical parts of the rollers; while sliding the casing the other way will permit the rollers to move outward from the bearing so that the pressure on the powdered lubricating material forming the plugs can be varied at the will of the operator.

The entire device is simple in construction, eiiicient in use, and will fill the perforations in a rapid manner, and with little expense.

I claim:

1. A pressure filler for oilless bearing comprising a holder adapted to receive a perforated tube, an arbor adapted to fit said tube, means to insert lubricating material in the perforations in said tube, and a roller adapted to apply pressure to said lubricating material after entering said perforations.

2. A pressure filler for oilless bearing comprising a holder adapted to receive a perforated tube, an arbor adapted to fit said tube and close the interior of said perforations, means to insert lubricating material in the perforations in said tube, and a plurality of rol'lers adapted to apply pressure to said lubricating material after entering said perforations.

3. A pressure filler for oillessbearing comprising a holder adapted to receive a perforated tube, an arbor adapted to fit said tube, and close the interior of said perforations, means to insert lubricating material in the perforations in said tube7 la plurality of rollers adapted to apply pressure to said lubricating material after entering said perforations, and means to adjust said rollers to apply pressure in varying degrees.

l4'. In a filler for oilless bearing, a pressure roller having conical ends7 and means to move said roller longitudinally, for the purpose set forth. Y

In a fillervfor oilless bearing, a pressure roller having conical ends whereby the radius of movement of the roller may be regulated, and means to regulate the radius of 392Mo y movement of said roller in connection with said conical ends.

6. The method of mounting lubricating plugs in a bearing comprising perfor'a'ting a tube, inserting saidvtube in a liolder,jplac fing an arbor in said tube'xvherebythe perforations are closed interiorly, and rolling lubricating material into said perforations.

7. The method of mounting lubricating plugs in a bearing comprising forming perforations in a tube,rmounting`the tube in a holder, placing an arbor in said tube whereby the perforations are closed interiorly, and rolling lubricating material into said perforations, the Vrollers being adjustable to apply pressure varying in degree.
